Switch filter bank integrated with interdigital strip line band-pass filters

The utility model discloses a switch filter bank integrated with interdigital strip-line band-pass filters, which belongs to the technical field of microwave communication and comprises a power voltage stabilizing circuit, a switch control circuit, two strip-line band-pass filters and two switch devices. The switch control circuit is used for driving the switch devices, the two strip line band-pass filters are connected in parallel between the two switch devices, the strip line band-pass filters are used for filtering signals of different frequency bands, and the switch devices are used for completing gating of the signals of different frequency bands. Compared with the prior art, the switch filter bank adopts the technical scheme of combining the switch device with the interdigital strip line band-pass filter, so that the technical indexes such as channel isolation and out-of-band rejection of the switch filter bank can be effectively improved, and the circuit size can be reduced. 本实用新型公开了一种集成交指型带状线带通滤波器的开关滤
